k8s搭建过程中使用的playbook

由于多台机器，每次都需要多次安装，使用ansible简单批量操作

k8s搭建过程使用ansible批量处理的playbook

前提

cat /etc/hosts
192.168.122.80   k8sMaster
192.168.122.82   k8sworker2
192.168.122.81   k8sworker1

/etc/ansible/roles/k8s/tasks/ConfigurationK8s.yml
cat /etc/ansible/hosts
[k8s]
k8sMaster
k8sworker2
k8sworker1
